What machine is used to dry wood?

The machine used to dry wood is called a wood drying kiln, or simply a wood kiln.

A wood kiln is a specialized type of oven that is designed to dry wood by removing moisture from it. The process of drying wood involves exposing it to heat and circulating air, which helps to evaporate moisture and reduce the wood's moisture content. This makes the wood more stable, durable, and resistant to warping, cracking, and other forms of damage.

There are several types of wood kilns, including conventional kilns that use electric, gas, or wood-fired heaters, and solar kilns that use the sun's energy to heat the wood. Each type of kiln has its own advantages and disadvantages in terms of cost, efficiency, and environmental impact.

Wood kilns are commonly used in the woodworking industry, as well as by hobbyists and woodworkers who need to dry wood for their projects. They can also be used for other purposes, such as drying food, herbs, and other materials.
